Assumption and Key
NCC 2019 prescribes different methods to determine Total R-value Calculations for Volume 1 and Volume 2.
The R-values shown are Total R-values for the building element as required by the Energy Provisions of the National Construction Code, calculated in accordance with AS/NZS 4859.2 2018 & NZS 4214. Kingspan Kooltherm® products are manufactured, tested and packaged in conformance with AS/NZS 4859.1:2018.
Product Testing
Characteristic | Standard | Result |
Compressive Stress (Insulant) | AS 2498.3 | Typically exceeds 100 kPa at 10% compression |
Water Vapour Resistance | BS EN 12086:1997 / I.S. EN 12086:1998 | > 35 MN·s/g
For the puspose of calculation of condensation risk, the resistivity of the fibre cement sheet component of the product should be taken as 250 MN·s/g·m. |
